Forecast Discussion: Current Conditions: As of 2 PM on Thursday, mostly cloudy skies prevail over the region as a frontal system remain draped across PA. We are seeing showers make their way through Ohio. The trajectory of these storms places much of the rain just south of our area. At the same time, there are some scattered showers popping up over northeastern US. As a result, we could still see rain impact our area later today. Right now, southwesterly flow coupled with the cloud cover is helping to keep temperatures confined to the upper 70s. Air quality levels have crept up into the moderate range, thanks to PM 2.5's ability to thrive in humid conditions. Expect these conditions to persist into tomorrow as it remain seasonably warm and humid. *** Friday's Forecast: So for Friday, mostly cloudy skies will continue to persist over the region as a frontal system slowly migrates across PA. The location of the frontal system with respect to our area will mean we will see another round of showers during the day. Afternoon temperatures will be limited (thanks to the cloud cover and rain chances) to the low 80s. Air quality levels are expected to remain elevated though with dewpoints hovering in the mid to upper 60s. Ozone levels will continue to remain low due to the cloud cover and rain chances. --Nolan
